Screening of Human Proteins for Fluoride and Aluminum Binding

Area of Science:

• Biochemistry
• Toxicology
• Computational Biology

Background:

• Prolonged exposure to fluoride (F-) and aluminum (Al3+) ions is linked to various diseases, notably neurological disorders.
• These ions lack known biological functions but can interfere with normal protein activities and downstream interactions.
• The specific human protein targets for F- and Al3+ have not been previously identified.

Purpose of the Study:

• To identify human protein targets that directly and indirectly interact with fluoride and aluminum ions.
• To explore the potential impact of these ion-protein interactions on biological functions, particularly in neurodegeneration.

Main Methods:

• Utilized data-driven prediction tools to screen for human protein targets interacting with F- and Al3+.
• Analyzed direct binding interactions and indirect protein-protein interactions.
• Investigated common protein targets between F- and Al3+.

Main Results:

• Identified 20 direct protein targets (10 for F-, 10 for Al3+).
• Discovered 86 indirect targets for F- and 90 for Al3+ through protein-protein interaction analysis.
• Found 19 common protein targets, with 9 implicated in neurodegenerative disorders.

Conclusions:

• This study provides a comprehensive list of potential human protein targets for fluoride and aluminum ions.
• The findings highlight potential molecular mechanisms underlying F- and Al3+-induced diseases, including neurodegeneration.
• Further experimental validation is required to confirm these predicted binding networks and their functional consequences.
